Hi Xiaoliang,
I think I can see what is going wrong.
PROBLEM 1
=========
At the end of step 1, you must add the new binutils to your path. So use
either
export PATH=/opt/or32/bin:$PATH
or
setenv PATH /opt/or32/bin:$PATH
whichever is appropriate for your shell. The first is for sh or bash,
the second for csh or tcsh.
PROBLEM 2
=========
In step 4, you need to copy Rich D'Addio's config file into .config
after applying the patches (you have missed this step in your
transcript). In the main Linux directory:
cp rgd_dot_config .config
This is almost certainly why your Linux will not build. You do not need
the "make defconfig" step (that will probably undo things). Just use
make menuconfig ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
and step through the menus to disable Ethernet. This is only done,
because of a known problem with Ethernet and the version of the
simulator you will be using. Then you should be able to build the kernel
with:
make vmlinux ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
PROBLEM 3
=========
You have not given the transcript for building Or1ksim, but I see you
have only downloaded the patches for GDB 6.8. These are incremental
patches IN ADDITION to the patches required to support earlier tools. So
you must first apply
embecosm-or32-or1ksim-0.2.0-patch.bz2
And afterwards apply
embecosm-or32-or1ksim-0.2.0-gdb-6.8v2-patch.bz2
One of the bugs fixed by the first patch was a problem handling xterms,
so that explains your crash. Even though your simulator runs with
telnet, you should rebuild including the first patch, since it also
fixes some silent faults in the modeling of the OpenRISC 1000.
I hope this enables you to get your system running successfully.
Best wishes,
Jeremy
